Wurlitzer 1600 Cobra cartridge

[retepknarf]

have a 1600 jukebox being renovated ,the amplifier is missing the oscillator (part number 49856) which is needed for me to use the Zenith cobra needles ,information I have found is ,2.5MHZ oscillator frequency ,Triod tube oscillator circuit .My knowledge on this is pretty poor so any help appreciated .

This system was used on several Wurlitzers which used cobra cartridges ,I know people have replaced this circuit to refit ceramic cartridges so may have the old parts around .

Thanks

The part number you are referring to is the coil in the oscillator circuit. Is this coil simply missing or have there been modifications done to use a different type of cartridge? That situation might likely throw up other issues! In any case I googled to see if I could find any technical info on the coil and discovered that Jukebox Revival in the Netherlands sell a replacement (maybe others do as well?)! Usually when modifications are carried out to the Cobra oscillator circuit, the redundant components are left in situ - in my experience!
